this question probanly has more to do with my lack of knowledge than anything else, but the lack is real!
, I work for a railroad as a conductor and have been trying to produce a program thta will handle time card submittals in a complex work rule environment.

The problem is working with time calculations. Am I wasting my time tryng to use the time edit functons in QT since I don't know how to access the elements of the widgets ,or should I just set up fields for the user to enter hours and minutes. i.e , no spin boxes
